Overview of the Digital Audio Tape Deck
Serial copy management system
This unit utilizes the serial copy management system
that permits digital-to-digital recording for one
generation. You can record CD sound or other digital
formats through a digital-to-digital connection. (See
page 36.)
Three sampling frequencies
Recording/playback can be done with three sampling
frequencies (48 kHz, 44.1 kHz and 32 kHz).
48 kHz: For analog and digital input signals in a
standard mode.
44.1 kHz: For compact disc and pre-recorded DAT
tape.
32 kHz: For analog input signals in a long-play mode.
Long play mode
This unit can operate in a long-play mode. Analog input
signals can be recorded or playback for up to four
consecutive hours when the DT-120 DAT cassette tape
is used. The sampling frequency will be 32 kHz in the
long play mode.
Visible cassette loading
You can view the tape operation through the lid of the
cassette compartment. Due to a revolutionary new
transport mechanism, cassette loading time has been
significantly reduced.
Excellent sound quality
¢ 1-bit A/D converter
For the A/D converter section which converts analog
input signals to digital signals, the unit employs a 1-
bit A/D converter which theoretically generates no
zero-cross distortion for a clear, elegant sound
quality.
Pulse D/A converter
Superior playback performance is achieved with a 1-
bit D/A converter.
Rich variety of subcode information
This unit can record subcode information such as Start
IDs, program numbers, Skip IDs, and absolute time
data, enabling you to quickly locate tunes and display
the playback time in the same manner as when playing
compact discs.
Post edit recording of sub codes
You can record or rewrite the following sub codes after
the audio signal recording has been completed.
Start ID: Signifies the beginning of a selection.
Program number: Gives a number to the selection.
Skip ID: Signifies the beginning of a portion to be
skipped.
End ID: Signifies the end position of recording/
playback.
Since sub codes are written on the tape separately from
audio signals, the audio signals are not affected.

Connections
This section describes about the connecting cords and the
analog and digital connections. Select the connection
depending on your equipment connected with this unit.
Rear Panel Jacks
LINE IN (line input) jacks (phono jack)
Connect to the recording outputs of an amplifier. Signals
supplied by the amplifier can be recorded using the
sampling frequency of 48 kHz in the standard play mode
or 32 kHz in the long play mode.
LINE OUT (line output) jacks (phono jack)
Connect to the DAT or tape inputs of an amplifier. The
piayback signal of this deck will be output.
COAXIAL/OPTICAL DIGITAL IN (digital input) jacks
(coaxial phono jack/optical jack)
Connectto the digital outputs of an amplifier having a built-
in D/A converter or other digital source, such as a CD
player for digital-to-digital recording.
OPTICAL DIGITAL OUT (digital output) jack
(optical jack)
Connect to the digital inputs of an amplifier having a built-
in D/A converter or another DAT deck, for playback of a
DAT cassette or digital-to-digital recording.
Notes on connection
e Use the connecting cords specified in the illustrations.
e@ Turn off the power for all equipments before making
connections.
e Be sure to insert the plugs firmly into the jacks. Loose
connections may cause hum and noise. When
unplugging, grasp the plug and not the cord.
Notes on the optical cable
@ Donot bend the cord. When the cord is not used, curl it
with a diameter of more than 15 cm (5 7/g inches).
e@ Do not use it under high temperatures.
@ When the optical cable is not connected, cover the
OPTICAL IN/OUT jacks with the supplied caps.
Note on sound signals
When connecting an optical cable to the DIGITAL IN/
DIGITAL OUT jacks, sound signals (L/R) are transmitted
together through the cable.
Connecting Cords
There are following three types of connecting jacks at the
rear of the deck. Each type of jack requires a different type
of connecting cord.

With conventional analog audio tapes, the tape portion on
which no recording ever has been made and the portion on
which a recording has been made but the sound is muted
are treated the same, since no sound can be heard from
these portions.
However, with DAT cassette, you should know that the two
kinds of “no sound" portions must definitely be
distinguished one from the other.

When recording, be certain that no blank section is left on
the tape. If blank sections remain on the tape, search
operations using the AMS buttons, for example, may take
quite a long time or the absolute time is not written
correctly.
Difference between the blank section and sound-muted
portion
When you record, a track format is constructed on the
recorded area, even if the sound is muted during
recording. On the blank section, since no recording is
applied, there is no track format.
Absolute Time Codes
The absolute time indicates the position of the tape, giving
the time elapsed from the beginning. The absolute time
codes correctly written on the tape can be used in various
convenient ways during playback.
Recording absolute time codes
When you record, the absolute time codes are also written
automatically from the beginning of the tape.
Once the absolute time codes are recorded, it cannot be
re-written. With the absolute time , you can check the
elapsed time from the beginning of the tape or designate
the position of the tape to be played back precisely.
Note, however, that the absolute time codes are not written
if you start recording from the middle of blank section. No
blank sections should be left on the tape when recording.
Tips for recording:
e@ To insert silence between selections, use the record
muting function (page 18). Do not advance the tape with
the mt or & button.
e Tostartrecording from the middle of the tape, use the end
search function (page 18) to locate the beginning of the
blank section. This will avoid leaving a blank section.
e@ When loading the tape written the absolute time codes,
the ABS TIME indicator is displayed, otherwise, the
counter indicator is displayed.
If a blank section is left on the tape
!f you start recording from the middle of a blank section, or
when the beginning of the new tape is advanced with the
»P or m button, the absolute time codes are not recorded,
since the DAT deck can no longer count the absolute time
from the beginning of the tape.

the actual recording/playback time.

Recording level adjustment (for analog input signals
only)
The peak level meters show the peak level of the analog
input signal held momentarily. The MARGIN indicator
shows how much margin there is between the peak level of
the input audio signal and 0 dB. Whenever a signal having
a higher level than the displayed one is input, the new level
replaces the lower one on the MARGIN indicator.

Using sound muted portion
If you intend to dub the DAT cassette onto an analog
cassette tape, we recommend that you insert sound muted
portions between selections on the DAT cassette.
This will ensure that the AMS function of the analog
cassette deck works correctly for the recorded tape.
Note
With DAT deck, the AMS function is realized by using the
start 1D code. (See page 21.)
To place a space on a DAT cassette, you must not advance
the tape with the mt or » button. If a space is created this
way, no absolute time code will be recorded on the
succeeding area, and you cannot check the elapsed time
of the tape.
To create a sound muted portion of more than 4 seconds
Keep the OREC MUTE button pressed for as long as you want to
make a recorded portion with no signals. After about 4 seconds,
the [REC] indicator flashes rapidly. When you release the OREC
MUTE button, the deck enters the record-pause mode.
The interval between selections is indicated in the MARGIN
display.
To create a sound muted portion of less than 4 seconds
Press the OREC MUTE button, and then the "PAUSE button while
the REC indicator is flashing.
To start recording in the rec mute mode
Press the @REC button while the indicator is flashing.

Writing sub codes
STU] ot Oxele (-1-)
in addition to the ordinary audio signals, various control
codes called sub codes can be recorded on the DAT
cassette tapes to ease recording and reproducing
operation.
A desired selection can be called up or time information
can be displayed using the sub codes, for example.
The sub codes such as start 1D, program number, skip ID,
end ID and program time and absolute time are available
on this unit.
e Sub codes are written on the tape separately from the
audio signals, so the audio signals are not affected.
@ Sub codes, except the absolute time, can be rewritten
after the audio signal recording has been completed.
The recorded audio signals are not affected by the rewritten
sub codes.
Start ID
This signal indicates the start of a music selection. You
can locate the position of the start ID precisely. This
signal should be written at the beginning of the
selection.
Program number
This signal gives a number to selection. You can record
it where the start ID is written. By designating this
number with the remote commander, you can choose
the desired selection directly or program selections in a
desired order.
@ When you record the tape with sub codes written onto a
new tape via digital-to-digital connection, the sub codes
to be written on the new tape are following:
The same as the codes written on
the original tape.
The same as the codes written on
the original tape.
New ones will be written according
to the DAT deck you use.
New ones will be written.
The one written on the original tape
will not be written.
When you use analog-to-analog connection, no sub codes
on the original tape will be written onto a new tape. New
codes will be written according to the DAT deck you use.
